PLOW.

SPECIFICATION forming part of Letters Patent No. 299,444, dated May 27, 1884. Application filed February 16, 1884. (No model.)

To ctZZ whom it may concern:

Be it known that we, THOMAS HARDEN WHITLOGK and CARROLL. LAFAYETTE ETHER- IDGE, citizens of the United States, residing at Paris, in the county of Henry and State of Tennessee, have jointly invented new and use ful Improvements in Plows, of which the following is a specification. I

Our invention relates to improvements in plows; and the objects of our improvements are to adapt the plowshare for adjustment to change itsangle with the standard, to'change the depth of cut, and to compensate for its the landside; to support it upon the landside; to provide for adjusting the latter with its plowshare upon the standard, and to effect these adjustments of the plowshare and landside upon a standard integral with a flat iron beam. The landside is formed of a thick L- shaped bar, and the plowshare is bolted directly to its vertical branch and adjusted vertically upon its front side, while its adjustment to varyits angle in relation to the standard is effected by turning the landside upon the bolts which secure it to the standard. The landside has an open recess on that side which joins the standard, and the bolt which fastens the plowshare passes through this open recess and allows for the vertical adjustment of the plowshare. Under this construction an adj ustable plowshare is combined with an adjustable landside and with an adjustable car rier supported upon the landside adapted to hold and. brace the share.

Referring to the accompanying drawings, Figure 1 represents a side elevation of a plow embracing our improvements; Fig. 2, a similar view, the handles and the colter and the plowshare being shown in different adjustments, in which thelandside and the plowshare are adjusted to make a deeper cut by turning the landside up upon its lower bolt; Fig. 3, a rear elevation; Fig. 4, the plowshare carrier and brace; Fig. 5, a side view of the landside, showing the plowshare carrier H thereon; Fig. (i, the plowshare; Fig. 7, a front view of the plowshare-carrier seated upon the front edge of the plow-standard and the front edge of the landside, and Fig. 8 the yoke which supports the handles.-

The plow-beam A is preferably of metal, with a curved integral standard, B.

O G are the handles secured by asingle bolt,

0, to the beam, and upon which bolt the said handles are permitted to turn. The landside D, with its shoe D, is preferably made in one piece, and it is secured to the plow-standard B by bolts d, which pass through slots d in the landside, and holes in the standard being secured by nuts f. The countersinks in the landside to receive the heads of the bolts (1 are made larger than the heads of the bolts, to permit of the adjustment of the landside.

Upon the inner side of the vertical portion of the landside is formed a recess, E, to receive the bolt F, which fastens the plowshare or mold-board G. This plowshare G may be of any desired form, and it'has at its top a cutaway portion or recess, G, and a series of holes, h, to receive the securing-bolt.

To prevent the lateral displacement of the plow-blade-that is, to prevent its turning upon the securingbolt after the same has been secured in proper position-a plate, as at H, having a lip or flange, I, at its top,which projects forward and rests upon the top edge in the recess G of the plow-blade, and two rearwardly-projecting ears or lugs, J, which lap at each side of the plow-standard, is interposed between the plow-blade and standard, and is held in proper position by the same bolt, F, that secures the plow-blade. To permit this plate to be adjusted to different lengths of plowshares or 1no1d-boards-that is, should the position of the bolt-hole in a different share vary-a vertical slot, H, is formed centrally through the plate H, through which slot the securing-bolt for the share passes, thus permitting the use of different-sized plow-shares 0 upon the plow, and also adapting the said share to have vertical adjustment, should it be desired to adjust it to increase the depth of cut of the same or compensate for wear.

K is a yoke for securing and holding the 5 plow-handles in their proper elevated position, and to permit the handles to beadjusted to different heights. This yoke isformed of a strip of metal having a central broad portion, K, which embraces the plow-beam, and two screw-threaded ends, L L,which are bent around over the handles, and are secured by a tie-plate, M, and nuts m. A bolt, N, is passed through the yoke just above the plow-beam, and, by its nut 12, forms the means for clamping the yoke upon the beam in any position it may be set. By this construction of devices for adjusting the plow-handles, no holes for bolts through the beam are necessary, and the weakening of the same is avoided; and to adjust the handles all that is necessary is to loosen the nut of the clamping-bolt N and push the yoke forward or backward and tighten the nut.

O is the colter, pivoted at its top end to the plow-beam by the same bolt,c,that secures the handles. A brace-arm, I, is pivoted at its lower end to the central portion of the colter, and at its top endis secured to the plow'handle. This colter O is formed of a-metal blade having a rearwardly-curved lower end, 0', which is similar in its position and operation to the wheel-colter. To permit of the vertieal adjustment of the colter to or from the plow, a series of holes, 0, are provided at its top end, and the free end of the brace-arm l is prot ided with a series of notches, p, which engage the staple Q, that holds the free end of said arm in proper position against the plow-handle. By this means the colter may either be adjusted vertically to compensate for wear or increase the depth of cut, or it may be brought nearer to or farther from the plow, which will be found desirable in case trashy or rough land is being worked, as the colter will act as a fender and prevent the covering of the plants by clods, trash, &c.

To adjust the plowshare, as described, the

bolts which secure the landside to the standard, as also the belt which secures the plowshare, are loosened and the top of the landside pushed either forward or backward, the slots for its securing-bolts d permitting of this movement, and then all the bolts are again secured. Vhen pushed forward, it will bring the plowshare into more of a vertical position, and consequently change the angle of cut, and, as seen in Fig. 2, the point of the land side will be more or less depressed below a horizontal line.

To adjust the plowshare to different heights, its securing-bolt F is loosened, and it is then adjusted vertically with its carrier-brace H,

when the bolt is again secured, by which means the depth of cut of the plow may be regulated or difi'erent-sized shares used without alteration of the parts.

It will be understood that the plowshare is secured directly upon the front side of the landside, which is a thick bar, having the recess E on its inner side joining the side of the flat standard, and that the slots d d are so arranged in the landsidc as to allow it to be turned in the arc of a circle upon its securingbolts (1 d and upon the standard, to cause the plowshare to dip more or less to suit the character of the soil.

\Ve claim 1. The landside having the slots d d and the open recess 15, combined with the plowshare G, the beam and the bolts dd and F, the said slots being arranged to allow thelandside to be turned upon its securing-bolts, substantially as described, for the purpose specified.

2. The combination, with the plow-beam, of the adj ustable landside D D, the plowshare G, the adjustable carrier II for the plowshare, and means, substantially such as described, whereby the plowshare and its carrier are secured to the landside, and the latter to the standard, substantially as described.

3. The colter curved at its lower end to ward the plowshare, combined with the brace P, pivoted to the colter near its lower end, having its upper end adjustably confined in a loop, Q, of the handle, the said colter being pivoted to the beam, and adapted to be adjusted vertically and to bring its curved end nearer to the plowshare, as may be desired, substantially as shown and described.

4. In combination with the beam and the handles pivoted thereto, the yoke K, embracing the beam having screw ends L L bent overthe handles, the clamping tie-bar M, connecting said endsbcneath the handles, and the bolt N, clamping the yoke to the beam, the said yoke being adapted to be adjusted by sliding on the beam and upon the handles to adjust and hold them, as shown and described. In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
